Abstract (en)
[origin: EP1351535A1] The uplink transmission timing from a mobile communications device is defined with reference to the downlink reception timing of signals from a first reference cell. When the first reference cell is removed from the active set, the uplink transmission timing is defined with reference to the downlink of a second reference cell remaining in the active set by choosing the time offset in such a way that the timing of the uplink transmission does not change. <??>This has the advantage that, following a soft handover, it is not necessary to adjust the timing of uplink transmissions from the user equipment. <IMAGE>
